The excessive buying of certain stocks is calledOverbought。KDJRandom indexOriginated from the futures market, it was invented by Georgelane and fluctuated between 0-100Overbought and oversold index, which is composed of three curves K, D and J, and is the KD value in practical application.KD values range from 0 to 100, which can be divided into: over 80 indicates that the closing price in the overbought area is too low, below 20 indicates that the closing price in the oversold area is too high, and the rest indicates that the closing price is wandering.
Overbought and oversold line(OBOS) is a measureequity marketIt is an analysis tool of fluctuation momentum, which can be used to study and judge by calculating the relevant differences of the number of fluctuationmarket index Indicators of future trends.Its advantages lie in simple calculation and concise analysis method, but it is very practical.OBOS indicatorsAvoiding index analysisMarketThe idea is to study and judge the market in terms of the number of ups and downs, and effectively eliminate a fewLarge cap index stockThe impact on the stock market, which more truly reflects the trend of the market.
1. OBOS (N)=Number of gainers - Number of losers in N daysBull market；When the OBOS value is negative, it indicates that the market is in the short market.When OBOS value>80, it means that the stock index has enteredOverboughtInvestors should pay due attention to investment risks;When OBOS value<- 80, it indicates that the stock index has enteredOversoldInvestors should pay attention to thereversalorreboundopportunity.
2. There is no absolute fixed standard for the specific value of OBOS overbought and oversold.Because China's stock market is expanding at a high speed and listed companies are also increasing, OBOS overbought andOversoldThe specific value of is also changing synchronously, but the total quantity standard is in the trend of increasing.
When the OBOS value>250, it indicates that the stock index has entered a serious situationOverboughtZone, when the OBOS value is less than - 300, it indicates that the stock index has entered a severely oversold zone.It is worth noting that although the indicators suggest seriousOverbought and oversoldHowever, investors should not implement the operation immediately, but waitOBOS indicatorsThe reverse signal appears.
3. Buying and selling signals of OBOS indicators.In most cases, the OBOS index fluctuates between - 80 and 80, and at this time, the index has no research significance.When OBOS entersOverbought and oversoldAfter the zone, even when entering a severely overbought and oversold zone, the reverse signal is effective.If the OBOS indicator reverses at this time and breaks through the OBOS indicator on the 6th dayaverageWhen it is on the 0 axis, it is a clear trading opportunity.
4. When the index runs in the same direction as the OBOS index, it indicates that the market development trend will be strengthened.
If both run upward, it means future marketquotationStill availableWatch too much；If both decline at the same time, it means that the future market still needs to be bearish.
5. When the index andOBOS indicatorsWhen the trend deviates from the characteristics, investors should always be aware that the trend may reverse.If the index is still rising while the OBOS index is falling, it indicates that there are a few mainstream funds in the marketLarge cap index stockTo boost the index and maintain popularity, while mostIndividual sharesHas taken the opportunity to escape, the market will soon weaken.If the stock index is falling while the OBOS index is rising strongly, it means that the decline of the stock market is caused by the suppression of the index stocks in the overall market, and the weight is not large at this timeIndividual sharesThe rise of indicates that the market is about to get warmer.
6. It is similar to the calculation principle of OBOS indicators, and has its own characteristics, which can complement each otherExponential smoothing broad index（STIX）、Rise fall ratio（ADR）、Tengluo Index（ADL）。When analyzingMarketWhether to see the historic important top and bottom positions must be used together for joint research and judgment.1. OBOS indicators reflect the overall operating trend of the stock market, which can eliminate the impact of index distortion and enable investors to grasp the best trading opportunity.However, this indicator does not provide a clear indication of the trend of individual stocks.Therefore, investors still need to solveStock selectionOnly in this way can we achieve the desired benefits.2. The defect of OBOS indicator is that it does not consider the marketcalorimeter In the index analysis,volumeAnalysis and market situation analysis are equally important. Therefore, when using OBOS indicators, if energy analysis can be combined, it will be more helpful toquotationAccurate research and judgment of the top and bottom.
As the name implies, "overbought" means that the number of people who buy shares has exceeded a certain proportion of the buyer's ability.Then, according to the "anti mass psychology" ("opposite opinion theory"), the stock should be sold in the opposite direction."Oversold" means that the seller oversold the shares. When the number of people selling shares exceeds a certain proportion, they should buy shares instead.This is the anti market and anti mass theory that is often most valued in the normal market.However, if the market is unusually strong, the overbought and oversold indicator will suddenly lose its direction and the market will keep moving forward.
In the stock market, it often appears that the spread of certain news makes investorsMarketorIndividual sharesMake a strong response, so as to cause the stock market or individual stocks to rise or fall excessively, and thenOverbought and oversoldPhenomenon.When the investor's mood calms down, the impact of overbought and oversold will gradually be properly adjusted.Therefore,OverboughtThen there will be a fall in the share price;OversoldAfter that, there will be a considerable rebound.If investors understand this overbought and oversold phenomenon and grasp its movement law in time, they can increase profit opportunities in the stock market.
